Sorting 2D matrix

Hello all,

I'm troubling with sorting of the matrix. I have a matrix

A  =   6.0000   18.0000   20.0000   23.0000   26.0000
       3.1464    1.4302    2.9512    0.9988    2.7403

I need to sort the second row in ascending order. Simultaneously the first row also needs to be sorted according to the second row like

required matrix = 23.0000  18.0000  26.0000 20.0000 6.0000
                  0.9988   1.4302   2.7403  2.9512  3.1464

when I trying to use the sort command like sort(A,2), I'm getting

sort(A,2)= 

      6.0000   18.0000   20.0000   23.0000   26.0000
      0.9988    1.4302    2.7403    2.9512    3.1464

Can you help me here. Thank you.

>> sortrows(A.',2).'
ans =
 23.0000   18.0000   26.0000   20.0000    6.0000
  0.9988    1.4302    2.7403    2.9512    3.1464

Thank you. It works

Indeed! :) Converts the rows to columns since sortrows is limited to selecting columns by which to do the sorting.

The brute force way w/ sort would be two steps...

[~,ix]=sort(A(2,:));   % get the indices for sorting 2nd row
A=A(:,ix);             % rearrange all by the column order
